Adaptive Machining Solutions


Manufacture and Overhaul of Turbine Components


The Solution

  • The damaged areas on the blade tips or leading edges are rebuilt by applying a welding bead to the effected area.
  • Each blade is located in a precision fixture.
  • The blade is then inspected on a CMM or by using On Machine Verification (OMV) right on the machine tool.
  • If no CAD data exists then the blade can be reverse engineered from point cloud inspection data. Alternatively a morphing process can be applied to the original CAD data, aligning the nominal data with the actual shape of the blade.
  • New CNC toolpath data is then created to machine away any excess weld.
  • A finish buffing operation is used to blend the remaining weld bead into the airfoil shape.
